Why Botox Might Not Last as Long in the Summer Heat (and What You Can Do About It)

Understanding Botox vs Fillers: A Quick Guide with Dr. Aimé

Hi, I’m Dr. Aimé, a plastic surgeon based in Scottsdale, Arizona. In today’s post, I’ll explain a common question I get in practice: What’s the difference between Botox and fillers?

Let’s break it down simply:

What is Botox?

Botox is a neurotoxin (also called a neuromodulator). That might sound intimidating, but it’s perfectly safe when administered correctly.

Here’s what it does:

• It blocks communication between nerves and muscles, causing temporary muscle relaxation.
• This helps soften dynamic wrinkles — the lines that appear from repeated facial movements like frowning or squinting.
• Common treatment areas include:
  • The forehead
  • Crow’s feet (around the eyes)
  • The glabella (the frown lines between your brows, often called “11s”)

So, Botox is all about reducing muscle activity to prevent and soften wrinkles.

What are Dermal Fillers?

Unlike Botox, fillers don’t affect muscle activity. Instead, they’re used to restore volume that naturally diminishes as we age.

Key facts:

• Most fillers are made of hyaluronic acid, a substance found naturally in our bodies.
• They come in different thicknesses, making them versatile:
  • Thicker fillers are ideal for midface areas like the cheeks, helping to lift and contour.
  • Thinner fillers are perfect for delicate areas such as the lips, under-eyes, or fine lines around the mouth.

Fillers reinflate and smooth the skin, giving a more youthful, refreshed appearance .

Botox or Filler — Which Should You Choose?

The answer depends on your goal:

• If the goal is smooth wrinkles from expressions, the recommended treatment is Botox‍
• If the goal is add volume to hollow or sagging areas, the recommended treatment is Filler‍
• If the goal is treat frown lines, forehead, or crow's feet, the recommended treatment is Botox‍
• If the goal is plump lips, lift cheeks, or contour jawline, the recommended treatment is Filler‍

It’s not uncommon for both to be used in a complementary way during facial rejuvenation treatments.
